# Language intelligence end to end: the helix keymap, the async round trip and
# the two dispositions of an answer.
#
# The backend behind the seam here is zls, run as a child process by the
# protocol client (it must be on PATH): `gd` is a request on a worker thread
# whose result comes back as an ordinary event, the same shape a pty read
# already had. Nothing in this script knows that: it presses keys and reads
# the grid, which is the point of the seam.
#
# a.zig is deliberately self-contained — a definition, a call site, and not one
# symbol from std — so these goldens do not encode this machine's stdlib
# version or its install path.
